WANTED: Native Irises (Iris tenax)

Hi everyone. I'm told that irises spread well and need dividing every year, so everyone ends up with extras. Does anyone have some native iris divisions to trade?

I'm specifically seeking Iris tenax, but I'd be interested in some of the irises that are native to other parts of the Northwest, like Iris douglasiana, Iris setosa or Iris chrysophylla.

If you are looking for something in return, let me know what kind of thing you're interested in and I'll see if I have anything.

Thanks!

I was given a native Pacific coast iris at a plant swap. The gardener was not sure what variety it was. Here is a photo. I also have lots of hybrid Pacific coast iris for trade. There are photo's on my trade list. If you are interested, LMK. Karen

Hi Thane, I went to the PCI society web site and keyed this out. This iris is I. douglasiana. Karen

Hi, I did find a pot of Iris tenax in my pot jungle. Are you still looking for it? If you are interested in it LMK soon. Pacific coast iris can only be divided when they are actively growing. Karen

Karen, yes! I would love some iris tenax. Those other irises look great too. I am emailing you directly. Thanks!

Is this true? Why would these iris be different from other iris? I am not trying to be argumentative, just trying to understand.

PS I came to this post because I was looking for information on the watering needs of Iris tenax.

Do they need summer water in the Willamette Valley (Oregon)?

Hi Nancy, yes the PCI are a little different from others. It goes dormant in the summer. If you divide them when they are dormant they die. Spring and fall when they are actively growing is the best time. You will see new white shoots on their roots. I usually divide mine late September or early October. The first year or 2 when you are getting a plant established it needs extra water. After that they are very drought tolerant. That is one of the reasons I started to grow them. I get tired of watering in our dry summers. Karen
